TZYB high-precision gear pump installation instructions: 1. Pump installation is good or bad, it has a very important impact on the smooth operation and service life of the pump, so the installation and calibration work must be carried out carefully, and must not be hasty. Brief description of mechanical installation of TZYB high precision gear pump
TZYB high precision gear pump installation instructions:
1. The quality of the pump installation has a very important impact on the smooth operation and service life of the pump, so the installation and calibration work must be carried out carefully and should not be sloppy.
2. The installation height, length and pipe diameter of the pump suction pipe should meet the calculated value, strive to be short, reduce unnecessary losses (such as elbows, etc.); and ensure that the pump does not exceed its allowable NPSH when it is working.
3. The suction and discharge lines should have a bracket. The pump is not allowed to withstand the load on the pipeline.
4. The location of the pump should be spacious enough for easy access.
TZYB high precision gear pump installation sequence:
1. Place the unit on the foundation with the anchor bolts, and use the pair of wedge pads for calibration between the base and the foundation.
2. Loosen the coupling shaft and place it on the pump shaft and base with the level meter. Adjust the wedge level to adjust the level of the unit and properly tighten the anchor bolts to prevent movement.
3. Correct the concentricity of the pump shaft and the motor shaft. The tolerance is 0.1 mm on the outer circumference of the coupling shaft; the clearance between the planes of the two couplings should be 2 to 4 mm, and the clearance should be uniform (small pump takes a small value). The tolerance is 0.3 mm.
4. After connecting the pipeline and determining the direction of rotation of the motor, connect the coupling and check the concentric square of the shaft.
5. After the actual test run of the unit for 2 to 3 hours, make a final inspection. If there is no bad phenomenon, the installation is considered qualified. Check the bearing temperature and vibration during the trial run as follows:
6. During the installation process, in order to prevent debris from falling into the machine, all the holes of the unit should be covered.
7. In order to prevent the impurities in the pipeline from entering the pump, for the newly installed pipeline, the filter should be installed in the pump glue, and the effective section should be 2 to 3 times larger than the section of the suction pipe.
